How to add float numbers using JavaScript?

In this article, you will understand how to add float numbers using JavaScript. Float values in JavaScript are defined as parseFloat(string).

Example 1

In this example, let's understand adding float values without using functions.

let inputFloat1 = parseFloat(2.3)
let inputFloat2 = parseFloat(3.5)

console.log("The two float values are defined as ", inputFloat1 ,"and", inputFloat2)

let result = inputFloat1 + inputFloat2
console.log("
The sum of the float values is: ",result)

Explanation

• Step 1 ? Define two float values inputFloat1 and inputFloat2.

• Step 2 ? Add the two float values using addition operator (+).

• Step 3 ? Display the result.

Example 2

In this example, let's understand adding float values without using functions.

function addFloat(inputFloat1, inputFloat2){

}
let inputFloat1 = parseFloat(2.3)
let inputFloat2 = parseFloat(3.5)
    
console.log("The two float values are defined as ", inputFloat1 ,"and", inputFloat2)

addFloat(inputFloat1, inputFloat2)

Explanation
